BMW E90 320i with 120 Ks on the clock looked after very well

regular 10K Liqui Moly Oil & Filter Change,
Regular Injector Cleaner,
98 Octance BP always,
spark plug changed at 100K,
CCV, Vaccum changed 100K

No Codes

But Car is driving sluggish, engine hesitates sometimes on freeway overtaking lanes, and also engine hesitates jerking feeling lol

Any idea what to look for?

Few things not changed are CAM, Oxy & Air Filter sensors. No Leaks

No codes... Hmmm... Is it an auto?

Could be coils... but no codes... could be auto box doing something fishy... but no codes... fuel filter? Cleaning injectors with aftermarket stuff might have made something in your engine a little dirty.

Engine hesitates, but no fault codes present. Unreal magic
Check it again

I would suggest a gearbox software update/Reset

It needs to be check properly by a workshop.
On top of my mind, only think they will not report a fault is AFM.

I am using Go Point technology Bluetooth Scanner and it not throwing any DTCs?

Same thing happened to mine - new set of (Bosch) coils and problem disappeared.
